*"For" operates like the adverbial conjunction "because," but it is usually considered a conjunction.

What are some of the differences between these types of sentence con­nectors?

Punctuation: Even though conjunctions and logical connectors have similar meanings, the punctuation for them is different. Conjunctions are preceded by a comma (,). Logical connectors are preceded by a semi­colon (;) or a period (.) and followed by a comma, as the following sen­tences show.

We ran to the bus stop, but the bus had already left.

We ran to the bus stop; however, the bus had already left.

You need to study hard, or you won't pass the test.

You need to study hard. Otherwise, you won't pass the test.

Position: Conjunctions always come between two independent claus­es. Some logical connectors may come in two other positions as in these sentences (notice how they are punctuated):

I've visited many countries in the world. I've never been to India, however.

I've visited many countries in the world. I've never, however, been to India.

Using neither, nor, never: When the conjunction nor connects two sentences, the word order in the second sentence changes to question word order rather than statement word order. This same rule applies whenever a negative word, such as neither or never, precedes a clause.

I haven't done the research paper yet, nor have I finished the required lab work.

John doesn't speak Spanish, nor do his parents.

Using paired conjunctions: Changes in word order are required with some of the correlative (paired) conjunctions from column 3 when they are used to join sentences.

Either you will have to quiet down, or you will be asked to leave the lecture.

Neither did he finish his research paper, nor did he take the final exam.

Not only is this the last time I'll help you, but it is also the last time I'll remind you to do this work.

Note: The change in word order is not necessary when joining parts of sentences:

Sally, my athletic sister, was good at not only tennis but also golf.
